Application filed July 9, 1919. Serial No. 309,532.

To all whom it may concern:

e it known that I, NJ'COLA Dn Rrrrs, a subject of the King of Italy,residing at Binghamton, in the county of Brooms and r 1: T State or howYork, have lnvented certain new and useful Improvements in RailwayTelephone Systems, of which the following is a specification.

This invention relates to certain new and useful improvements in railwaytelephone systems and has for its primary object to provide meansassociated with a trolley pole adapted to be extended laterally of a carfor engagement with a telephone wire horizontally arranged. adjacent thetrack.

A further object of the invention is to pr0- ride a railway telephonesystem in which there is provided an apparatus associated with a trolleypole and embodying a hinged element normally overlying a car and whichmay be distended for engagement with an adjacently positioned telephonewire whereby an occupant of the car may use a telephone while the car iseither stationary or under operation.

With the above and other objects in view, the invention consists in thenovel combination and arrangement of parts hereinafter fully describedin connection with the accompanying drawings, and in which likereference characters designate corresponding parts throughout theseveral views.

In the drawings, 7

Figure 1 is a side elevational view of an electric car track, trolleywire and telephone wire with the present invention carried by thetrolley pole and in operative engagement with the telephone wire,

Fig. 2 is a top plan view thereof showing the forked end of the wireengaging head for obtaining a double connection,

F 3 is an enlarged top plan View of a trolley pole and telephone armattached thereto, a portion of the telephone wire being shown andengaged by the forked head of the telephone bracket arm,

Fig. i is a side elevational view of the form shown in F 3 showing thespring arms for limiting the lateral swinging movement of the forkedwire engaging head and the hinge joint between the two sections of thetelephone bracket arm,

Fig. 5 is a longitudinal sectional view of a portion of the telephonebracket arm showing the swivel connection between sections of the arm topermit slight relative rotary more" tion aims to ments, the hingeconnection midway of the 7 ends of the arms and the spring arms forholding the fork head in alinement with the main portion of the arm, and

Fig. 6 is a cross sectional view taken on line VIVI of Fig. at showingthe swivel connection between sections of the bracket arm.

It is understood that the present invenprovide an apparatus associatedwith cars that receive their power through the medium of a trolley pole,and wherein the apparatus carried by the trolley pole is adapted to beprojected at any time desired for engagement with an adj acentlyarranged telephone wire and electrical apparatus carried by the car andadapted to be set into operation by the engagement of the apparatus withsaid telephone wire whereby an occupant of the car may have use of atelephone while riding upon a trolley car, or while the same is at astandstill, this electrical feature of the invention embodying circuits,eto., not entering into the details there of, he present inventionresiding solely in the apparatus for forming the connection between thetelephone wire and the car.

With this idea in view, and with particular reference to the drawings,the reference letter A designates the car of any preferred constructionoperating upon a track 13, a trolley wire C being arranged over thetrack to be engaged by a trolley pole attached to the car.

The trolley pole 10 is pivotally mounted at its lower end upon the stand11 carried by the top of the car A and suitably tensioned as desired,the outer or upper end of the trolley pole 10 being provided with across head 12 for engagement with the trolley wire 0, the head beingemployed instead of a wheel so as to insure the proper engagement of thetrolley pole with the wire at all times. i

A. tubular post 13 is arranged parallel to the trolley pole 10 and issecured thereto by clamps 14, the same being bodily movable with thetrolley pole 10. An outwardly directed arm 15 arranged at right anglesthereto is preferably formed integral therewith, an angle brace 16 beingassociated with the post for purposes of bracing the same. The arm 15 isof tubular and sectional formation, the same being provided intermediatethe ends thereof with a hinge connection. 17 whereby the outer section15 may be folded upwardly and downwardly upon the inner section of thearm, and when outwardly positioned, as shown in Fig. 4:, the lowershouldered portions 18 of the hinge connection 17 will prevent the outersection 15 from falling below the horizontal axis of the inner section.

A forked head 19 mation and of hollow construction carries a tubularstem 20, the inner end of which is pivoted at 23 to opposite sides ofthe outer arm section '15 have the free ends thereof engaging the stemportion 20 of the forked head at points outwardlyof the pivot 21, thepressure of the springs being equal so that the same normally extends in'alinement with the arm 15.

1n order to permit slight oscillatory movements of the forked head 19,there is provided a swivel connection in the arm 15, a portion of thearm 15 shown more clearly in Fig. 5 being reduced as at for telescopicreception in the adjacent portion of. the arm while opposite sides ofthe periphery thereof are provided with recesses 25 into which extendthe ends 26 of set screws 27, this construction being shown more clearlyin Fig. 6.

During normal operation of the car and trolley pole, the outer section15 of the hracket'arm is folded inwardly to be sup ported by the innersection thereof and when it is desired to use the telephone, the

outer section 15 is moved upon the piyotlT until the connection 18operates to hold the arm sect ons in horizontal position. When soarranged, the free bifurcated ends 28 of the forked head 19 are inposition to engage the telephone vire 29 supported upon bracket 30carried, by the poles 31 as is clearly illustrated and when so arranged,electrical. connections 'to the telephone. D are established by thewiring 32 passing through the tubular post '13 and arm and' forked head19 with the wire engaging the substantially of U-lliOY-r as at21 to theouter end of the outer arm section 15 while flat 5 3IJ.11'S 22 fixed asI a tubular post, mounting telephone wire as shown in Fig. 3. Due tovarlatlons in the track structure, and possible deflections in thetelephone wire 29, the hinge connection 21 will permit hori-. zontalmovement of the forked head which will be limited and cushioned by thesprings 22 while slight oscillating movement in vertical directions willbe permitted by the swivel connection 25 and 26 in the arm 15. l Viththe circuit established as above described, a person in the car may haveready use of the telephone while the car is either standing still or inoperation and when it desired to break the circuit, it is only necessaryto move the outer section 15 of the arm upon the pivot 17 to cause thesame to overlie the-inner section with the forked head positionedadjacent the trolley pole 10;

While I have herein shown and described the preferred embodiments of myinvention, it is nevertheless to be understood that minor changes may bemade in the form, combination and arrangement of parts with outdeparting from the spirit and scope of my invention as claimed.

lVhat I claim as new is 1. An auxiliary trolley pole comprising bracketstherefor, an integral outwardly directed arm carried by the upper endthereof, a vertically swinging extension carried by the outer'end of thearm,- .and alaterally swinging head resiliently mounted at the outer endof the extension.

2. An auxiliary trolley pole comprising a tubular post, mountingbrackets therefor, an integral outwardly directed armcarried by theupper end thereof, a Vertically swinging extension carried by the outerend of the arm, said arm including a joint adapted for limited rotatablemovement, a head swingingly mounted at the outer end of the extension,and spring arms carried by the extension engaging the head to hold the
